SPECIFICATION forming part of Letters Patent No. ecsns anatea May 1, 19oo.'

Application filed Pebrnary ZO, 1900. Serial No. 5,909. (No model.)

To all whom it may concern? Be it known that 1, JOHN EDMOND Jones, a citizen of the United States, anda resident of North Bridgewater, in the county ofv Oneida and State of New York,,have invented a new and Improved Plow Attachment, of which-the following is a fnll,,clea r, and exact description.

.This invention'relates to improvements in attachments for plows ;'an (1 one object is to provide a simple means to prevent the plow from jumpingoutof a furrowshould the point strike a stone or the like; further, to provide rollers, one forward and one rearward of the share, withmeans for simultaneously rais.-.

ing or. lowering them, the said means being controlled by hitched to the 1 after appear. 4

I will describe a plow attachment embodying myinvention and then point outthe novel features in the appended claims.

' Reference is to be had to the accompanying having an attachment embodying my invention; and Fig. 2-is a side elevation, partly in 1 section, showing the parts in a different position from that shown in Fig. 1.

livotally connected to the forward portion of the beam 1 of the plow are U shaped han g-.

ers 2 3, one being arrangedon each side of the beam and the pivot connection with the beambeing through the forward arms of the hang ers, while the upwardly-curved rear arms engage against the sides of thc'bcam, so as to prevent lateral displacement. A roller 4 has its bearings in the lower portions of the hangers, and from a rod 5, connecting the rear portions of the hangers, a link I; extends toa pivotal conucction with an angle-lever 7, here shown as extended lhroughan opcningin the plow-beam and operating on a pivot-bar extended across said opening. The upper member S of the angle-lever is provided with alougitmliual slot to rcceivea pin or the like fl, extended from a draw-bar 10. The drawbar l0 extends rearward through a guide '11, and at its rear end connects with a frame plowshare.

thenioi'ements of the animals Other objects and advantages will herein draw-bar.

I comprising side members 12 13, pivoted to the rear portion of the plow-beam. The draw-bar is shown as engaging with a cross-rod 14,

which connects the upper portions of the frame members 12 13., In the lower portion of the frame members a roller 15is journaled, this roller'of course being rearward of the A spring 16 is attached at one end to the-draw-bar and at the other end to the guide-platell, said spring serving'to,

move the draw-bar rearward, as will be hereinafter described. v the draw-bar extends through a guide-plate The forward portionof I 17, attached to the front end of the beam,

and the draw-bar has a return member 18, which also extends through the guide 17. The draw-bar and member 18 are each provided with a series of perforations, into either one of which pins 19 may be inserted toregu-' late the amount of forward movement of the A pole or tongue 20 has a universal-joint connection with the draw-ban] .As here shown, a-soeket 21 is attached to the forward end of the draw-bar, and the rear end of the pole or tongue is provided with a ball 22, which will prevent the pole from being drawn outof engagement with the socket. A shifting lever 2.3 has pivotal'connec'tion "with the draw-bar and is also pivoted at its lower end to the plow-beam, and a latch 24, movable vertically 011 the lever, is designed to engage in either one of aseries of notches formed in a segment-rack 25, attached to the plow-beam. I

In operation when the 'p'low is drawn forward the parts will be substantially in the position shown in Fig. 1, and as the plow in passing through a furrow, the rear roller 15 .be'iug engaged with the sides of the furrow slightly above the bottom, will prevent the plow from jumping out of the furrow laterally should the plow-point strike a stone or other obstruction. Should the plow by any means jump upward outpf the furrow and then sidewise out of it, it is only necessary to cause the d raft-animals to back, so that the ball 22 on the pole 21.) engages wit h the rear wall of the socket 21. As the animals are backed the draw-rod l0 will be' moved rearward, which will cause both the front and rear rollers to be moved downward below the plane of the plowsharo, as iudical' d in Fig. 2. Then the plow will be easily moved farther backward on its rollers by the draft-animals and without any exertion on the part of the man attending the plow.

Shouldit be desired to draw the plow along a road or over ground without plowing, the

lever 23 is to be drawn backward and the latch 2!. moved into engagement with one of. the notches of the rack 25, which will hold the two rollers in their lowermost position. The degree of height of the rollers above the lower portion of the plowshare may be-regulated by shifting the pins 19 in the perforations in the parts and 18. v

It maybe here stated that when the draftanimals are caused tp back and before the ball 22 shali have reached the rear wall of the socket the-spring 10 will have so acted on the draw-bar as to move the rollers into their lowermost position.

Ipreferablymake the pole or tongue 20 of tubular iron, and by employing the'pole or tongue it is obvious that, as before stated the plow map be moved backward by the animals and, fur he'r, as the whiffletrees are mounted on the pole they cannot fall to get underneath thehorses feet.
